Thirteen genes (IGF2BP, HIST1H3E, CUBN, ADCY4, ZNF804A, HIST1H1A, NOX4, CYP24A1, GLIPR1L1, CHODL, PLSCR4, CDH26 and RAD54B) overlapped between a study of blood-derived DNA methylation [25] and the study of tumor vs normal breast tissue of different breast cancer patients [35] but differed in the identified DMP. This evidence concerns the gene CHODL and breast cancer.
